Patented Mar. 28, 1950 2,502,281 RAIL FASTENING DEVICE Otto Sann, J ohnstown, Pa., assignor to Carnegie- Illinois Steel Corporation, a corporation of New Jersey Application June 11, 1947,. Serial No.753,984 "I and more particularly to such a device for fasten- In mines and quarries much of the railroad track used is moved to new positions as work advances. To facilitate the assembly and disassembly of this track, the rails are set upon metallic ties. Since the ground surface is frequently rough and the track extends over considerable areas, detachable pieces: used to fasten the rail to the tie become mislaid or lost. Since parts storage is ordinarily not available this causes delay in assembling the tracks. Nonresilient rotatable clips are normally used to fasten the rails to the tie and if they are not lost they become loose and ineffective after they have been used several times.

It is an object of my invention to provide a rail fastenin device in which the rail fastening means are permanently fastened to the tie.

Another object is to provide such a device in which resilient clips are used to fasten the rail to the tie.

These and other objects will be more apparent after referring to the following specification and attached drawings, in which:

Figure 1 is a top plan view;

Figure 2 is a sectional elevation taken on line II-II of Figure 1; and

Figure 3 is a sectional view taken on the line III-III of Figure 2.

Referring more particularly to the drawings the reference numeral 2 indicates a metallic tie on which is mounted a rail 4. A pair of clamps 6 is rigidly secured to the tie 2 on one side of the rail 4 with one end of the base of the rail being received in a socket 8. A depression I is provided in the tie 2 on the opposite side of the rail 4 and an inverted U-shaped member I2 is welded to the tie 2 at a point between the depression In and the base of the rail. A spring clip l4 passes through an opening I6 in the member l2 and extends from both ends thereof. The clip I4 has an arched construction and that end adjacent the rail 4 has a turned-up portion IS. A downwardly extending projection is provided adjacent the portion 18, the projection and turnedup portion having a greater overall height than the inner height of the member I2. The opposite end of the clip is provided with a downwardly extending protuberance 22, the thickness: of the clip at this point being greater than the inner height of the member l2.

In assembly the spring clip I4 is laid on the tie 2 and the inverted U-shaped member I2 is placed 4 Claims. (Cl. 238.349)

Over the top thereof and welded to the tie 2. If

electrical flash or spot welding methods are used, sheet insulating and fireproof materials are placed between the clip 14 and the member I2 to prevent the clip from adhering to the member [2 durin welding. Gas welding or electric arc welding does not require this insulation. Due to the dimensions of the ends of the clip I 4 it cannot then be removed or become loose from the tie. In fastening the rail to the tie, the spring clip I4 is forced from the dotted line position shown in Figure 2 to the full line position, the arched construction of the clip being such that it is compressed between the under surface N5 of the member 12 and the socket l0 and the top of the rail flange. In this position the end l8 of the clip extends over the top of the rail flange with the projection 20 hearing against the end of the rail flange and the protuberance 22 rests in the socket ID. This construction prevents the clip M from backing out from the position shown in full lines in Figure 2 while the semi-elastic characteristic of the clip permits a certain degree of undulation under traffic and a certain amount of vertical movement of the rail without the clip being sheared off. When it is desired to remove the rail, a crowbar or other device is used to force the clip l4 from the position shown in full lines to the position shown in dotted lines in Figure 2.

While one embodiment of my invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departin from the scope of the following claims.

I claim:

1. A rail fastenin device for fastening a rail to a metallic tie, which device comprises an inverted substantially U-shaped member securely fastened to said tie, an elongated spring clip extending through said inverted member and projecting from both ends thereof, one end of said clip adapted to extend over the flange of the rail, 9. downwardly extending projection adjacent the last mentioned end of the clip, said projection being adapted to bear against the end of the rail flange, the end of said clip including said projection having a greater overall height than the inner height of the inverted member, and a downward protuberance at the opposite end of said clip, the thickness of said clip at said protuberance being greater than the inner height of the inverted member, whereby said spring clip cannot be removed from the U-shaped member.

2. A rail fastening device for fastening a rail to a metallic tie, which device comprises an inverted substantially U-shaped member securely fastened to said tie, an elongated spring clip extending through said inverted member and projecting from both ends thereof, a turned-up por tion at the extreme end of said clip adjacent the rail, a downwardly extending projection adja cent said turned-up portion adapted to bear against-the end of therail flange' said projection and turned-up portion having a greater overall height than the inner height of the inverted member, and a downward protuberance at the opposite end of said clip, the thickness; of said clip at said protuberance being greater than the inner height of the inverted member, whereby said spring clip cannot be=renfovedfrom the U shaped member.

3. A rail fastening device for fastening. a rail to a metallic tie, which device comprises an inverted substantially U-shaped member securely fastened to said tie, an elongated spring clip extendin vthrough said inverted member and projecting from both ends thereof, a turned-up portion atthe extremeendof said clipadjacent the rail, a downwardly extending projection adjacent said turned-u portion adapted to bear against the end of the rail flange, said projection and turned-up portion having a greater overall height than the inner height of the inverted member, and a downward protuberance at the opposite end of said :clip, the thickness of said clip at said protuberance being greater than the inner height of the inverted member, whereby said-spring clip cannot be removed from the U- shaped member, said tie having a pocket therein for receiving said protuberance.

4. A rail fastening device for fastenin a rail to'a" metallic tie according to claim 3 in which said cli-p hasan arched construction.
